MAINTENANCE / CLEANING
Special maintenance is not necessary. However, to
maintain performance over many years, the optical
system should always be carefully cleaned. Coarse dirt
particles, such as sand, should be removed with a fine
hair brush or blown away. Marks such as fingerprints on
the front lens and eyepiece lenses can be cleaned with
a damp cloth and then wiped off with a soft, clean leather
or dust-free cloth. Special cleaning cloths, as used for
glasses, are not recommended. They are impregnated
with chemicals that can damage optical glass and its
coatings (the glass used to make glasses has a different
composition from the types of glass used in spotting
scopes). Alcohol and other chemical solutions must not
be used to clean the housing. If necessary, wipe with a
soft, dry cloth. For excessive soiling, your Apo-Televid
can be cleaned simply by rinsing it under running water.
Saltwater can be rinsed off in the same way.
Note:
To protect the front lens – particularly from severe
environmental influences (such as salt water) – it makes
sense to use an E 67 / E 82 screw in filter.
